I am compiling OpenCV 3.4.1 in my Raspberry Pi 3b+. I have downloaded both opencv and opencv contrib. This is the build command I give : (ABSOLUTE NEWBIE in compiling using cmake and OpenCV)

cd ~/opencv-3.4.1/
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE \
      -D CMAKE_INSTALL_PREFIX=/usr/local \
      -D INSTALL_PYTHON_EXAMPLES=ON \
      -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.4.1/modules \
      -D ENABLE_PRECOMPILED_HEADERS=OFF \
      -D BUILD_EXAMPLES=ON ..

After the building process is over, the compilation process still uses python 2.7 interpreter. What other option should I add to compile it using python3. I looked on stackoverflow and found this :how to build opencv for python3 when both python2 and python3 are installed But since it does not have a correct answer I am a bit skeptical.

Followed this guide : https://www.deciphertechnic.com/install-opencv-python-on-raspberry-pi/

Using Python 3.5.3

Please ask for any further info that is required. Thanks.

    It usually tells you after the cmake is done like a report and tells which version will be used. You can also use ccmake to change specific parameters a reconfigure it. look for the python params Commented Feb 26, 2019 at 12:59

    Possible duplicate of I have 2 versions of python installed, but cmake is using older version. How do I force cmake to use the newer version? Commented Feb 26, 2019 at 13:18
